My solution was...

build.sbt

import play.sbt.PlayImport.PlayKeys.playRunHooks

lazy val gulpDirectory = baseDirectory {
    _ / "admin-panel"
}

excludeFilter := HiddenFileFilter -- ".tmp"

unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / "dist"}

unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / ".tmp"}

unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / "bower_components"}

//this is for development environment
unmanagedResourceDirectories in Assets <+= gulpDirectory { _ / "src" / "app"}

playRunHooks <+= gulpDirectory.map(path => Gulp(path))

project / Gulp.scala

import play.sbt.PlayRunHook
import sbt._

import java.net.InetSocketAddress

object Gulp {
    def apply(base: File): PlayRunHook = {

        object GulpProcess extends PlayRunHook {

            val gulpFile = "gulpfile.js"
            var process: Option[Process] = None

            override def beforeStarted(): Unit = {
                if (isWindows) {
                    Process("cmd /c gulp build", base).run
                } else {
                    Process("gulp build", base).run
                }
            }

            override def afterStarted(addr: InetSocketAddress): Unit = {
                if (isWindows) {
                    Some(Process("cmd /c gulp serve", base).run)
                } else {
                    Some(Process("gulp serve", base).run)
                }
            }

            override def afterStopped(): Unit = {
                process.map(p => p.destroy())
                process = None
            }

            private def isWindows: Boolean = {
                System.getProperty("os.name").startsWith("Windows")
            }
        }

        GulpProcess
    }
